Abstract [en]

The purpose of this study was to attempt to date a sediment stratigraphy by examining the possibility for correlation with the results from a previous study using tephrochronological methods. Tephrochronology is the studies and methods which identifies and dates tephra (volcanic ash) in strata for use as a synchronization tool between various sediment stratigraphies. In this study, analysis of organic carbon, XRF scanning, extraction and microscopic examination of tephra and an attempt for chemical analysis by electron microscopy was conducted of a drill core from Fågelmossen in southern Sweden. Tephra was found in the bottom of the drill core and by using this finding, combined mainly with the analysis of organic carbon, the drill core stratigraphy could be correlated with the results from the previous study.
